Apple Testing 'Clamshell' Foldable iPhone Alongside Book-Style Model

Apple is reportedly testing a clamshell-style foldable iPhone alongside its book-style foldable, potentially expanding its future foldable lineup, though mass production remains undecided. According to Weibo leaker Fixed Focus Digital, Apple is developing a clamshell design similar to early flip phones, in addition to the book-style iPhone Fold. The clamshell model offers higher portability by folding into a smaller form factor, with an external screen for notifications and iOS widget integration. Apple's first foldable iPhone, expected in Q4 2026, is likely to adopt the book-style design, providing a larger unfolded screen for tablet-like use. The clamshell variant may follow depending on market reception. Apple is also planning to launch the iPhone 18 Pro and Pro Max in Q4 2026, with standard iPhone 18 slated for Spring 2027.
